EXERCISE FOR PEOPLE OVER 60.
Begin by standing on a comfortable surface, where you have plenty of room at each side.
With a 5lb potato bag in each hand, extend your arms straight out from your sides, and hold them there as long as you can. Try to reach a full minute, and then relax.
Each day you'll find that you can hold this position for just a bit longer. After a couple of weeks, move up to 10lb potato bags.
Then try 50lb bags, and then eventually try to get to where you can lift a 100lb bag in each hand, and hold your arms straight for more than a full minute. (I'm at this level.).
After you feel confident, at that level, try putting a potato in each bag.
